My own campaigns have never been very fiend-heavy, so I haven’t delved much into the ranks of devils, but as I’m looking at the merregon for the first time, I’m impressed by the idea that the souls of soldiers who served evil spend eternity fighting for the forces of hell without faces, only permanent iron masks.
